In binary liquid mixtures, the growth of wetting layers can be limited by diffusion. At complete wetting, the distance l between the interfaces bounding the layer is shown to grow as l(t)~=Atfor large times t where Aincreases near the consolute point. In three dimensions where this growth...
We propose a new type of morphological instability in the diffusion-limited growth of faceted crystals from the vapor phase that can explain the formation of thin ice plates at temperatures near -15 C. The instability appears when the attachment kinetics for facet growth depends strongly on the ...

The existence of a different vibration band of H3BO3 in FTIR confirmed that growth structures are related to boric acid. XRD pattern has shown broad peak along with some sharp peaks. Broad peak is related to starch???s amorphous nature, as where intense sharp peaks are due to boric acid....
Diffusion-limited aggregation (DLA) is a model which represents noisy growth limited by diffusion. This process is quite common in nature and the simple algorithm gives a good representation of the large-scale structure of many natural objects. The clusters grown in the computer and the real ...
A two-dimensional square lattice computer model was used to study the cluster growth process by irreversible aggregation on the boundary of a shear flowing colloidal solution. The trajectories of the aggregating particles are determined by both a diffusion component and the streamlines of the flow. ...
In turn, L-Systems have been mainly applied in generating self-similarity graphical models [11], and also to study different plant growth patterns [12]. In the last years, the research community has focused the attention on alternative applications of these two techniques. In the case of DLA...
We consider an island growth mechanism wherein species adsorbed on top of two-dimensional islands diffuse to the edge and are then incorporated. A simple matrix formulation is developed for this random-walk problem which allows exact calculation of the growth probability distribution, neglecting island...
Computer simulations have been used to explore two-dimensional diffusion-limited aggregation models in which growth is allowed only at the tips of needle shaped arms that are directed away from the origin. For the case of two adsorbing needles with growth velocities equal to the rate at which th...
